I created a service class that outputs movie files to the browser and I tried clearing the output buffer before I output the file but when I do that and click another page while the movie is playing I get an error.
Here is the main code that outputs the video from my service:
ob_clean();
flush();
ob_end_flush();
// Vars
$filePath=realpath($file->getFileLocation());
$chunkSize= 1 * (1024 * 1024); // How many bytes per chunk
$buffer='';
$fileHandle=fopen($filePath, 'rb');
while (!feof($fileHandle))
{
$buffer=fread($fileHandle, $chunkSize);
echo $buffer;
//ob_flush(); flush();
}
fclose($fileHandle);
And here is the error I am getting:

I noticed that THttpResponse is doing some output buffering stuff by the error I am getting above by why does that break and show the error above when I try clicking on a link while a page is playing a movie that I am sending from my application?
Thanks.
